Description

Iron Oxide (Fe₃O₄) Micron Powder, Purity: 99.5+%, Size: 1 µm

Product Description:
Iron Oxide (Fe₃O₄) Micron Powder, also known as magnetite, is a chemically stable, highly pure magnetic material with a particle size of 1 µm and a purity level exceeding 99.5%. This fine black powder exhibits strong ferrimagnetic properties, making it ideal for use in both research and industrial sectors.

Thanks to its unique inverse spinel crystal structure, Fe₃O₄ combines excellent magnetic behavior with electrical conductivity, enabling its application in magnetic storage devices, microwave absorption materials, and electromagnetic shielding components. The high surface area of micron-scale particles enhances reactivity, dispersibility, and processability in formulations.

In the biomedical field, micronized Fe₃O₄ is commonly used in magnetic resonance imaging (MRI), magnetic hyperthermia, and drug delivery systems, owing to its biocompatibility and ability to respond to external magnetic fields. Its versatility also supports applications in catalysis, gas sensors, pigment production, and electrochemical systems such as lithium-ion and sodium-ion batteries.

Fe₃O₄’s magnetic and optical properties make it suitable for ink formulations, smart coatings, magnetorheological fluids, and advanced electronic components where stability and controllability under varying magnetic fields are critical.
